Thanks, Jin. Appreciate it. Yes, I'll begin with Page 3 and the highlights of our Q1 results, and I begin by saying, we had a good start to the year with another strong quarter of performance. Earnings per share were $1.23 on a GAAP basis and $1.26 excluding the impact of the divestiture costs related to the announced spin-off of our Lighting business. At $1.26, our results were 15% above last year and toward the higher end of our guidance range, which as you will recall was $1.18 to $1.28. Our sales were $5.3 billion, up 4% organically and in line with our guidance, excluding the negative 3% impact from currency. And we continue to be pleased with our strong margin performance. Segment margins were 16% above the high end of our guidance range and 80 basis points over prior year. We also generated very strong operating cash flows of $551 million in the quarter, and this is up 63% from Q1 2018 and a first quarter record. And lastly, we repurchased $150 million of shares in the quarter as part of our plan to buy back $400 million of shares in 2019. So, a very good start to the year. Page 4 summarizes our income statement versus prior year. And I've covered most of these items in the summary comments and so I'll only point out once again, the 3% currency impact was driven primarily by the important currencies for us which are the euro, renminbi and real. We are very pleased with our 32% incremental rate that we delivered on organic growth. And so, that number was, once again, very strong and above our expectations. And we incurred as we mentioned, the $0.03 per share from the after-tax cost primarily related to the spin of our Lighting business. And as you can see adjusted earnings per share increased from 9%. Next, we summarize the quarterly results of our Electrical Products segment. Revenue here increased 2%, which includes 5% organic growth, partially offset by 3% currency. And we see particularly strength here in commercial and in residential construction with global growth rates in the mid-to-high single-digits and even stronger in the U.S. markets. Our orders increased 4% led by continued stroke, strength and growth in the Americas and our backlog grew double-digits, up 13% in the quarter. Segment operating profits grew 8% and operating margins were 120 basis points increase to 18.9% and this was a record for Q1. And we are actually pleased with how well the segment is performing and the consistency of results that we continue to see in this part of the Company. Moving to Page 6, we cover our Electrical Systems & Services results. Revenues here increased 6% with organic growth of 8%, partially offset by 2% currency and we saw especially strong double-digit revenue growth in commercial construction and in data centers. We continued to have solid momentum in this business and the year had started on a high note for sure. You will recall that our original guidance is for sales to be up 5% to 6% organically for the year, and so we are certainly running above that rate. As we indicated at our Investor Conference in March, we have moved to a rolling 12-month basis for reporting our orders in this long-cycle business, as well as in our Aerospace business that I'll cover soon. On a rolling 12-month basis, ES&S orders actually increased 8% with strength in all major end markets and regions. And maybe, I'll just pause for a moment on the orders here in the Electrical Systems & Services because I know it's a particular point of question that many of you have and I will tell you that our ES&S activity level is absolutely performing in line and perhaps maybe even a little bit better than what we anticipated. And we talked about this idea of moving to the rolling 12 months, because we do in fact see a lot of, let's say, call it lumpiness in the orders that we get in Electrical Systems & Services driven primarily by what we are seeing in hyper scale data centers. And the other indicator that we have that gives us a lot of confidence in the strength of this business is, is what we call negotiations. And our negotiations in this business in Q1 were an all-time record and up some 56% from prior year. And so despite what we are seeing actually in the orders and what some of you have reported to be a little bit of weakness versus what we saw in Q4, the overall underlying activity in this business continues to be very, very strong. Our backlog continued to grow, it was up 11% in the quarter. We generated strong operating leverage with operating profits increasing 15%, only 8% volume growth and margins increasing a 100 basis points to 13.1%. You will also recall that we announced the acquisition of the Ulusoy Electric business in January. We are pleased to have closed the purchase on April 15th and then this acquisition will certainly provide a strong platform for us as we serve our customers in EMEA and the Asia-Pacific markets. So once again, a really strong performance in our Electrical Systems & Services business and we continue to be quite bullish on the - for the outlook for that business as we go forward. On the next Page, we summarize our Hydraulics results for Q1. Revenues were down 3%, with 1% organic growth more than offset by a 4% currency. I'll certainly note that we had some tough comps in this business at 6% organic growth in Q1 2018, but revenue did slow slightly more than we expected, but I would probably note here only slightly more than what we had in our original plans for the year. Organic growth of 1% reflected continued growth in construction equipment, but some declines in Ag and in industrial equipment. Our orders stepped down 11%, driven principally by weakness in global mobile equipment markets and we also had tough comps here as well from last year, where orders were up some 14%. Backlog declined 6% in the quarter as well. And as we detailed at our Investor Conference, we continue to work through some inefficiencies in the business, but do expect to see strong margin performance in this business in the second half of the year as we work off some of the efficiency issues that we experienced in the second half of last year. And segment margins were 11.7%, down 100 basis points versus last year. And on Page 8, we summarize our Q1 results for the Aerospace business. And as you can see, this business just continues to perform at a very high level, delivering record performance across almost every single metric. Our revenues increased 10%, a 11% organic growth and 1% negative currency. Like ES&S, we moved to a rolling 12-month basis for reporting orders. And on this basis, orders increased 18% with particular strength in commercial transport, military fighters, military transport and both commercial and military aftermarket. So really strength across the board in this segment. Our backlog also increased significantly, up some 21% in the quarter. And lastly, we demonstrated very strong incremental margins with labor to add to a 30% increase and operating profits and a 300 basis point margin improvement in the quarter. Operating margins of 23.1%, another all-time high for the business. So in addition to the volume growth, we also experienced some favorable product mix in the quarter, but really strong execution by the team overall. Next, I'll move to a summary of our Vehicle segment. Our revenues were down 9%, which includes 6% reduction in organic growth and a negative 3% from currency. The organic sales decline was driven by a combination of declines in like global vehicle markets, which were down 45% and the ongoing impact of revenue transfers to the Eaton Cummins joint venture. And I will note that the joint venture actually saw revenue increases of 27% in the quarter and continues to perform very well. We also had tough comps in this business with organic growth, which increased 13% last year. But overall, this business is really performing as we have expected, but with a little bit of weakness in global automotive markets. For the year, we continue to expect NAFTA Class 8 production to be at 324,000 units, flat with 2018. But we have lowered our outlook for light vehicle markets for the year. And lastly, despite the lower volumes, operating margins increased 30 basis points to 15.1% and a decrement of margin on the organic of less than 20%. So really strong execution by the team, once again, in our Vehicle business. And wrapping up our segment summaries, we will cover our eMobility segment on Page 10. Revenues were up 8%, which includes 9% organic growth, partially offset by 1% currency. And as planned, we continue to accelerate our R&D spending, which increased by some 130% in the quarter. So we continue to invest heavily in this segment to participate in what we think is really an exciting growth opportunity as we move forward. We are certainly optimistic about the opportunities in this rapidly developing market, and our pursuit pipeline for new programs has actually now grown to $1.1 billion. At our Investor Conference in March, we did announce a new program win of a $100 million mature year revenue for traction inverters with a major global OEM customer and actually in mid-April, we announced that PSA is the customer for this program. This was our first significant event, since creating the segment about one year ago, and we are certainly ahead of our original schedule for growth in this segment and well on our way to accreting what we think is going to be a new $2 billion to $4 billion segment for the Company overall. At this point, I'll turn to our outlook for 2019, which is on Page 11. We now expect organic revenues for all of Eaton to grow approximately 4%, down slightly from our prior midpoint of 4.5% and this is largely the result of us increasing our guidance for our long-cycle businesses by reducing guidance for our short-cycle businesses. Specifically, we increased organic growth rates by 1% for both ES&S and Aerospace. And for Hydraulics, we lowered organic growth by 2% at the midpoint to 3% to 4% based upon some slow growth expectations in global mobile equipment markets. And for Vehicle coming off, what I would say really was a weak Q1 in light vehicle markets, we lowered our organic growth rate by three points at the midpoint, and now we expect organic growth to be down some 4% to 5%, and once again, due to primarily the automotive side of the business itself. And we have not changed electrical products or eMobility. And our margin expectations are noted on Page 12. We are modestly raising our guidance from 17.1% to 17.5% or 17.3% at the midpoint. We are lowering the margin expectations for Hydraulics by 60 basis points to 13.4% to 14% and for Vehicle by 90 basis points to 16.5% to 17.1% due to lower organic growth primarily. But this is more than offset by increases in Electrical Products and in Aerospace margins. Our new expectation for Electrical Products is for margins to be between 19% and 19.6%, a 50 basis point increase at the midpoint and the new expectation for Aerospace is for margins to be 21.8% to 22.4%, also a 40 basis point increase at the midpoint. And the other two segments remain unchanged. So at the midpoint, 17.3% and this would naturally be another record level of performance for Eaton overall. And lastly on Page 13, we summarize our guidance for Q2 and for the year. For Q2, we expect adjusted earnings per share to be between $1.45 and $1.55 and at the midpoint, this represents an 8% increase over last year. Other assumptions in our guidance include, we are expecting 4% organic growth, foreign exchange impact of roughly $100 million. Our margin expectation for the quarter is that have margins between 17.2% and 17.6%. We would expect our corporate cost to be flat with Q2 of 2018 and we would expect the tax rate of between 13.5% and 14.5%. For the full-year 2019, we are raising our adjusted earnings per share guidance to $5.72 to $6.02 for the midpoint of $5.87, which includes essentially a $0.02 impact from the full-year impact of the acquisition of Ulusoy overall. At the midpoint, this continues to represent a 9% increase over 2018. Other full-year guidance assumptions include organic revenue growth of 4%. We would expect $100 million of revenue from the Ulusoy acquisition. We expect foreign exchange impact to be $300 million and this is a $50 million increase from prior guidance. We would expect, as I mentioned, segment margin of 17.3% and really no change to the other items in our forecast. So in summary, I would say another strong start for the year in Q1. We are well positioned to deliver another year of record results and we are absolutely thrilled with the way that the Company is performing overall. So with that, I'll turn it back to Yan for Q&A.
